Triangular mug and advertising means

ABSTRACT

A beverage container having at least two curved sides which meet at rounded lengthwise edges, having improved pouring and liquid flow characteristics, which may be used with a sealed lid and is capable of being tightly nested with other like shaped containers. The container also presents increased and improved outer surface areas, which more readily facilitate commercial or advertising graphic imprinting. The container comprises an inner and outer shell with the outer shell and may further include a snug fitting lid to facilitate the use of the container for travel.

BACKGROUND OF THE INVENTION

The present invention relates to a new container for beverages which may be used for hot or cold liquids and permits its user to more readily access the liquid in the container, pour liquid from the container in a more uniform manner and store or package groups of containers in a significantly more compact space than conventional drinking cups or mugs. The base of the present invention is sized for convenient use during travel as it fits in most, if not all standard automotive cup holders. Additionally, the geometry of this container design readily facilitates the imprinting of graphical images or text on numerous surfaces which each consist of larger radii curved surfaces which reduce the distortion of the printed image and increase the usable space for such imprinting.

Insulated cups or mugs for use as beverage containers are well known. Such containers are commonly used as drinking vessels for hot or cold beverages. On occasion, these types of containers are also used as an advertising medium whereby graphical material such as a company logo are imprinted on the side of the container about its circumference. A significant disadvantage of the existing mugs and cups is that they are typically configured in a round cylindrical shape. Such a shape is inherently disadvantageous because the conventional circumferential shape does not facilitate easy pouring of the liquid in a concentrated stream or other pattern from the container, thereby increasing the propensity of the liquid to overspill from the container. The present invention also provides the user with the option of receiving liquid from the apex of two adjacent sides, thereby permitting a more controlled flow of the liquid for easier consumption, particularly of hold beverages. The present invention also may include a sealed cover lid so as to facilitate its portability for carrying beverages the container with less or no spillage.

In addition, the circular shape is not an efficient use of space and requires significantly more cubic space in which to package a group of identical containers, such as for shipping, than would an array of closely nested triangular shapes.

Lastly, the round cylindrical shape of conventional mugs or cups does not easily facilitate the imprinting of graphical material for many reasons. As the circumference of the mug presents a highly curved surface about a relatively small radius, it is prone to distortion of the printed image. Additionally, as the circumference is one continual surface, there are no clear demarcation characteristics on the container outer surface, about which one may print multiple independent images in a non-confusing fashion. The present invention, having its outer surfaces of a more coplaner convexity than a conventional round container, presents greater total surface area upon which one may imprint than does a conventional round container having the same average outside diameter and the same overall height.

For the foregoing reasons, there is a need for a beverage container that is constructed in a non-circular shape, such as a triangular cylindrical configuration, which provides improved pouring characteristics, more compact nesting shape, convenient size for fitting in a cup holder and which has improved surfaces on which one may imprint commercial or advertising text or graphics.

SUMMARY OF THE INVENTION

The present invention provides for a beverage container comprising an insulated vessel having an inner shell and an outer shell which are rigidly adhered to one another so as to create an insulating cavity in the open space between the inner and outer shell. Both the inner and outer shell are formed as an elongated cylinder with a triangular cross sectional shape having rounded edges. An additional embodiment of the invention includes a sealed lid to present the invention as a travel drinking container for use with hot or cold beverages.

The present invention satisfies the needs for a small personal use sized insulated beverage container from which a liquid may be poured in a uniformly controlled flow with reduced spillage when compared to conventional drinking containers. With its triangular shape and rounded edges, the pouring of a liquid from the invention, with the flow emanating from the top opening at a rounded comer formed by intersecting arcs of adjacent triangular sides, is funneled into a uniform flow such that the beverage may be poured from the container in a safer, more accurate and controlled fashion than that from a conventional round container. This feature provides the user with improved control of the flow which is particularly important to reduce spilling accidents when consuming hot beverages. In addition, the present invention is sized such that its base will fit in commonly found automotive cup holders.

Further, the present invention satisfies the need for improved cost and efficiency related to shipment and/or storage of multiple similarly shaped triangular containers in both commercial and home locations, as its shape facilitates improved nesting between containers, thereby requiring less volume within which a group of containers may be kept when compared to conventional round cylindrical beverage containers.

The present invention also satisfies the need for an improved beverage container to serve as an advertising or commercial device, having the advantages of less imprint distortion, greater imprint surface area and more discrete surfaces on which to imprint when compared to conventional beverage containers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, a perspective view of a preferred embodiment in the configuration of a Triangular Mug with a lid is illustrated. As indicated above, although the preferred embodiment is depicted as a triangular cross section, the invention may be of any non-circular geometric shape and would still possess each of the key attributes of the invention. The Triangular Mug embodiment comprises an inner shell (1) having one open end and an outer shell (2) having one open end, with both inner and outer shells being elongated cylindrical components and having a triangular overall shape as shown in FIG. 2. The three comer lengthwise edges (6) between adjacent triangular faces of the outer shell (1) are rounded, so as not to present a sharp or distinct line edge shape along the three lengthwise edges (6) where the three arcuate triangular sides of the outer shell (1) converge. The inner shell (2) includes a inwardly chamfered or beveled top edge (7), sloping inward toward the open inside diameter of the inner shell. This top edge (7) is rounded and of the same radii profile so as to conform to the rounded lengthwise edges (6) to form a uniform and streamlined appearance of the edge profile from the bottom of the outer shell (1) to the top lip of the inner shell in the area of the top rounded pouring edge (8). The outside surface of the outer shell (2) presents three distinct surfaces on which imprinting may be presented, those being the surfaces along the length of the outer shell (2) between each of the three rounded lengthwise edges (6).

The lid (4) of the Triangular Mug, as shown in FIGS. 2, 4 and 5, comprises a triangular lid cover including a male lower end (5), which extends down into the inner shell when the lid is mounted on the Mug. The outer surface of the male lower end (5) has a flexible lipped seal (5 a) which is inserted into a groove (5 b) or other similar radial cavity formed in the outer diameter surface of the male lower end. The lid (4) also includes displaceable member (9), the displacement of which alternatively accesses or prevents access to a small orifice (10) through which the user may drink the encapsulated beverage. In one embodiment, the displaceable member (9) is a sliding plate which includes a protrusion (11) which the user grasps to displace the displaceable member (9).

As illustrated in FIG. 6, the inner shell (1) and outer shell (2) are rigidly affixed to one another by adhesion through common methods known to those skilled in the art, at the circumferential mating surface (3). The affixture of the inner shell (1) to the outer shell (2) forms a closed cavity (13) between the inner and outer shells, to facilitate the insulation characteristics of the invention.

In Alternate embodiments of the invention could include one or both of the inner shell (1) outer shell (2) or both inner constructed of a polymer based material or of a metallic material. The inner surface of the inner shell (2) may be a triangular cross sectional shape so as to correspond to the shape of the mating outer shape or the inner shell (2) may have a round cylindrical shape, of an outside diameter such that it may reside radially inside and within the outer shell for affixing the inner shell (1) to the outer shell (2).

In another embodiment, the closed cavity (13) may be evacuated during assembly and affixture of the inner shell (1) to the outer shell (2) so as to create a vacuum in the cavity (13) for improved insulating capability of the invention. Alternatively, This cavity (13) may be filled with a material commonly known to those skilled in the art, so as to enhance the heat transfer characteristics of the Mug to maximize the invention's capability to maintain the contained beverage at or near a desired temperature.

In yet another embodiment, the invention may include a top ring (12) which is snugly fitted about the top of the lid (4) so as to present a streamlined and smooth edge of the invention to prevent nicks or damage to the otherwise exposed top circumferential edge of the lid (4).

While the triangular configuration is discussed and depicted in the drawings, any non-circular geometric shape having at least two distinct sides is contemplated within the scope of the invention. Having side portions with mating edges results in the invention's key features of pouring edges, nesting and handling as described above. In addition, each of the distinct sides would present an excellent surface for the imprinting of advertising or graphical materials for the purposes of advertising or promotion.
